Performance Estimation of MIMO-OFDM for New Radio signals IN LTE Networks for Precise indoor signaling

Abstract

Considering that the radio frontend system for an indoor BS consists of both the RF amplifier circuit as well as the antenna subsystem, it is imperative that the study of compact antennas and their practical implementations becomes further more relevant with the advancement of wireless technological advancements. In this context, the study of high efficiency Single Input Single Output (SISO) antennas has already been carried out for modern wireless BS. Further, efficient Multi-Input Multi-Output (MIMO) antennas are also being used for many high power and medium power BS applications. Additionally, there are popular applications of multi-band antennas for different wireless technologies. In the modern indoor BS, it is becoming a design requirement increasingly to integrate more than one wireless technology, such as Long Term Evolution-Advanced (LTE-A) and Wireless Fidelity (Wi-Fi), into the same hardware. This poses a huge challenge to the hardware and system integration aspect to encompass the multiple MIMO antennas supporting multitechnology requirements while adhering to the high isolation co-existence related radio impairments in a compact form factor. The combined challenge of meeting the high isolation in an efficient and compact size of the radio system is another key focus of this study.
